About this calculator

Public Provident Fund is a 15-year small-savings account. You can deposit up to ₹1,50,000 in a financial year. The government sets the interest rate every quarter. For October to December 2026 that rate is 7.1% a year. Edit the rate box when a new quarter is notified.

This calculator assumes the whole yearly deposit is in place at the start of the year and earns that year’s rate. The real account looks at the lowest balance between the 5th and the end of each month. A deposit after the 5th does not earn interest for that month. The table is still a clear way to see deposits and interest separately.

The account is meant to be held to maturity. Extension is in blocks of five years. Do not use this page to plan a loan against PPF or a partial withdrawal. Those have their own limits.

A contribution may be eligible under the old tax regime’s investment deduction. The default new regime does not allow that deduction. Interest and maturity treatment should be checked in the return you actually file.

How this PPF estimate is built

Each year the model adds the deposit, then adds interest = balance × rate.

This matches a deposit made at the start of the year that earns a full year of interest. The official method is stricter: interest is calculated each month on the lowest balance between the 5th and the last day, and it is credited at year end.

Deposits above ₹1,50,000 in a year are capped in this tool.

Example: ₹1.5 lakh a year for 15 years

₹1,50,000 at the start of each year for 15 years at 7.1%.

Total deposited is ₹22,50,000.00. Illustrated maturity is ₹40,68,209.22. Interest is ₹18,18,209.22.

If you deposit later in the month, the post office balance that earns interest can be lower than this model. Treat the maturity as an upper-style planning figure for a start-of-year deposit, and confirm the live rate.

FAQ

What interest rate does this use?

The box defaults to 7.1%, the rate notified for October–December 2026. Change it when the government notifies a new quarter.

Why might my passbook be lower?

Interest uses the lowest balance between the 5th and the last day of each month. A deposit after the 5th waits until the next month. This model assumes a full year on the yearly deposit.

Can I deposit more than ₹1.5 lakh?

The tool caps the yearly deposit at ₹1,50,000 and tells you when it has done so. Amounts above the limit are not part of the PPF rules used here.

Is PPF tax-free in the new regime?

The new regime does not allow the old deduction for the contribution. Check the current treatment of interest and withdrawal in the income-tax material for your year. This calculator does not file a return.
